Application filed June 9,

My invention relatesto a' cap adapted to form aclosure for a bottle or .other container. More. particularly, it relates to a cap formed of a single piece of resilient sheet metal drawn to shape and adapted to be snap ed into position on the container.

An 0 ject of the present, invention is to provide an improved form of cap having greater resiliency and awider range of elasticity than caps of this type heretofore 1n use.

Other objects ofthe invention will appear hereinafter.

In the accompanying drawings:

Figure 1 is atop plan view of a cap construced in' accordance with my invention.

Figure 2 is a side elevationof the cap.

Figure 3 is a sectional elevation of the same. Y Y a Figure 4 shows a bottle with a cap in-position thereon.

Figure 5 is a bottom plan view of the cap.

The construction herein set forth embodies certain features discl sed in my 'co-pendmg application, Serial umber 694,514, filed February 23,1924. a 1

The cap is preferably .stamped out of flat sheet metal and drawn. to its finished. shape. It comprises a concave circular to 10, the periphery 11 of which is curved downward to provide a flange. portion which fits over the lip of a bottle 9. The flange of the cap has kerfs or cut-away portions 12 at regular intervals around the cap% providing an annular series 0 spring tongues or tabs 13 which are curved inward to engage beneath the'lip of the bottle. The

lower ends or tips of said tongues are curved outwardly to assist in placing the cap on the bottle and to increase the stren th and resiliencyyof the tongues. One of tile ton es is extended to form a finger piece14. liner 17 of cork or other suitable material is placed within the cap. I

By reference to Figures 1 and 5, it'will be observed that the outline or periphery of the cap is not a-true circle, but approximates a polygon, being approximatel shape in the particular formo cap shown. That is to say, the tabs 13 as seen /in plan view are somewhat. flattened or have longer the SP1 portion thereby hexagonal radii .of curvature than the radius of the cap. Also the .outlineof the cap at the dius of curvature than the radius of the cap.

As a result of this widening of the curvature of the tabs 13, they are considerably more resilient than'when curved concen-.

trically with the cap and can also be sprung outwardly to a, greater extent without liability of tearing the metal at the upper ends of the kerfs or otherwise injuring or permanentlyldistorting the cap. -Also, with this construction, a more certain and reliable sealing of the bottle can be obtained and the cap will-more readily accommodate itself to variations inthe'size and shape of the lip of the bottle-to which it is applied.

Modifications may be resort d it and scope of my invention. What Iclaim is:

1.; A bottle ca consisting of a single piece of resilient sheet metal comprisin a top to within portion and an annular flange port1on,- s"aid k flange portion comprising an annular series of spring holding tabs or tongues each curved about an axis parallel with the main axis of the cap, and each having a greater radius of curvature than the radius of the cap.

2. A cap consisting ofa single piece of] sheet metal comprising a circular convex to portion and a flange portion, the periphcra portion of the cap which unites the top and flange portions being in the'form of a wide curve, said flange portion comprlsing an an-'" nular series of spring holding tabs separated by kerfs which extend upwardly into said peripheral portion of the cap, said eripheral portion bein ap roximately'po ygonal in outline, the si esp the poly on forming thebases of said tabs-and eac having itsradius of curvature of ater length than the radius of the cap, sai sides-merging into each other at the bases of the kerfs.
